Summary of the invention
Can't bear high temperature, high pressure for what overcome that existing copper strap wire exists; And the problem that mechanical performance is limited, the existing special manufacturing process that proposes the strong corona-resistant polyimide film sintered enameling copper strap wire of a kind of temperature resistant grade height, proof voltage grade height and mechanical performance.
For realizing the foregoing invention purpose, the concrete scheme of manufacturing process of the present invention is following:
A kind of corona-resistant polyimide film sintered enameling copper strap wire manufacturing approach is characterized in that step comprises:
A, copper conductor is processed, processed copper strap wire: earlier copper coin is delivered in the copper coin holding furnace, copper coin holding furnace temperature is 1150 ~ 1180 ℃; Cover deoxygenation on the copper coin surface with the charcoal that toasted, cladding thickness is 100～150mm, and copper coin is melted into copper liquid; Crystallizer is inserted the copper liquid degree of depth 130～140mm, and the water inlet device begins water inlet, and inflow temperature is 30 ℃～35 ℃; Intake pressure 0.20～0.35MPa; But after the moulding, bar traction air pressure 0.25 ~ 0.30MPa is drawn in the sabot of draw bar traction moulding circle line base in the copper liquid cooling;
To justify the line base through continuously extruded formation flat type copper wire, in the extrusion production, compaction pressure is 40MPa, the frock cooling, and temperature is lower than 60 ℃, and Current Control is lower than 180A, and extrusion temperature keeps 470 ~ 500 ℃.
B, copper strap wire is processed 200 grades of compound enameling copper strap wires of polyester-imide/polyamidoimide: at copper strap wire surface-coated insulating varnish, copper strap wire from inside to outside respectively japanning be polyester, polyester-imide, 3 types of insulating varnish of polyamidoimide, total insulation thickness of japanning is 0.12 ~ 0.16mm; Japanning passage 12 times altogether; Japanning passage ratio is 5:3:4, after the japanning baked and cured, forms paint film; The per pass film thickness is even; Be controlled between 0.010 ~ 0.015mm, the described solidification process center line speed control of baking and banking up with earth is built in 2 ~ 6 meters, and temperature control is: 120 ~ 130 ℃ of fire doors; 240 ~ 260 ℃ of following warm areas; 360 ~ 390 ℃ in middle control district; 400 ~ 410 ℃ of last warm areas.
C, outside enamelled wire behind the wrapped corona-resistant polyimide film heating bake and bank up with earth, sintering: i.e. wrapped the and sintering process of film, corona-resistant polyimide film adopt lap width be 50% or lap width 2/3, overlapping wrapped mode; Wrapped through high-frequency apparatus, temperature is 250-350 ℃; Perhaps the baking oven heating is baked and banked up with earth sintering, temperature 200-280 ℃; Time is 15-20 minute.
The invention has the advantages that:
1, the present invention has combined two kinds of different processes of enamel-cover and Bo Bao, i.e. B step (enamel-cover) and C step (glass bag) have broken through the limitation of traditional handicraft; The anti-corona intensity of product is high; Temperature resistant grade is high, has remedied existing single type performance, and the two is well combined.
2, in the steps A because the fusing point of copper is 1083.3 ℃, and the too high meeting of temperature makes the intensity of material and plasticity that bigger decline arranged, temperature is crossed and is hanged down material and can not melt fully, so and consider that region factor temperature is chosen as 1150 ~ 1180 ℃.According on draw the capacity deoxygenation charcoal of smelting furnace interpolation thickness be 100 ~ 150mm, this is that CO is a toxic gas because too much charcoal can the too much CO of output, this very big potential safety hazard of inflammable and explosive such existence, too much charcoal adds also can increase cost.Add not thorough oxygen of then deoxygenation and copper generation chemical reaction less, so the Promethean value of the application is 100-150mm; It is the shape of under the situation of saboteur's structure not, utilizing the recrystallization temperature of copper to relocate that extrusion temperature keeps 470 ~ 500 ℃ reason, if temperature is too high, the life-span that then can shorten frock increases production cost.
3, three kinds of different lacquer ratio 5:3:4 are the japanning ratios for the present invention's original creation in the B step, under this japanning ratio, and the tack of finished product, voltage breakdown, temperature resistant grade is best.The per pass film thickness is controlled at viscosity and the levelability decision of 0.01 ~ 0.015mm according to lacquer; Guaranteed the smooth per pass of product surface; Surface quality was coarse when film thickness increased, and japanning then is difficult for the total insulation thickness of maintenance again when reducing 12 passages, can reduce the tack and the electric property of product.Tack has this very big requirement to the paint film of per pass, and insulation thickness total among the present invention is in 0.12 ~ 0.16mm scope.
4, the lap width of film improves the electric property of product to greatest extent for being tight in order well to be wrapped on the copper cash sealing in the C step.Wrapped through high-frequency apparatus, temperature is 250-350 ℃; Perhaps sintering is baked and banked up with earth in the baking oven heating, and temperature 200-280 ℃ combines film and copper cash together, and cryogenic product can not well merge the electric property that also can reduce product like this.
5, the corona-resistant polyimide film sintered enameling copper strap wire of the present invention's production, through copper strap wire surface-coated insulating varnish is processed enameling copper strap wire, the wrapped again corona-resistant polyimide film of going up cures sintering through heating, and film and enameling copper strap wire are fused into one.Temperature resistant grade is high, the proof voltage grade is high and mechanical performance is strong.On the basis of common enamelled wire, increase the corona-resistant polyimide film sintering, increased corona-resistance property, improved dielectric strength, electrical strength simultaneously.
6, be that the patent of invention of CN200810143364.X is compared with number of patent application, also there is following difference in the present invention: annealing temperature of the present invention is meant that copper strap wire annealing after-tack reduces Brinell hardness.And extrusion temperature is meant, the shape of utilizing copper under 470 ~ 500 ℃ recrystallization temperature, to change copper is better passed mould, processes the dimensional accuracy height, the copper strap wire of any surface finish.The japanning passage is identical with dipping lacquer step repetition notion, but temperature control is different, and the present invention is 4 grades of temperature controls, and method of lacquering is also variant, and what the present invention adopted is the felt japanning, and finished product each item index performance that the present invention produced is better.
